Consider Century Roof And Solar if...
- ✓ Your project involves both roofing work and solar installation, requiring coordination between roof condition assessment, structural upgrades, and panel placement under a single contractor
- ✓ Your roof is older than 10 years or you're uncertain about its condition, and you want one experienced contractor to evaluate structural readiness before committing to solar
- ✓ You prioritize long-term service reliability and want a contractor with a 30-year track record and demonstrated responsiveness for post-installation support
- ✓ You're planning related upgrades like skylights, ventilation, insulation, or gutter work alongside your solar project
Consider Power On Solar if...
- ✓ Your project is solar-only and your roof is newer, in good condition, and recently inspected by a qualified roofer
- ✓ You're working with specific equipment preferences like SunPower or Enphase systems and want a contractor focused exclusively on solar technology
- ✓ You have relationships with other trades for any roof or electrical work needed and can manage coordination yourself
- ✓ You're willing to establish clear service terms in writing and verify emergency contact protocols before signing, given the service responsiveness concerns in customer feedback
Questions to Ask Before Hiring
- → Ask Power On Solar directly about their service response process: What's your typical response time for system issues after installation? Who is my service contact, and how do I reach them if panels stop producing?
- → Ask Century Roof And Solar to clarify their solar service capabilities: Do you handle monitoring, troubleshooting, and repairs in-house, or do you coordinate with a solar partner?
- → For either company, request references from solar installations completed 2-3 years ago and ask those homeowners about their experience with any service needs that arose
- → If choosing Power On Solar, ask what their contract specifies about service timelines and whether they offer a dedicated service phone line or online portal for existing customers
The Bottom Line
If your project involves any roofing work or uncertainty about roof condition, Century Roof And Solar is the clear choice—their 30 years of roofing expertise, demonstrated service reliability, and ability to coordinate both trades under one contract provides substantially better risk management. For solar-only projects on roofs recently confirmed to be in excellent condition, Power On Solar offers specialized solar focus, but the recurring service responsiveness concerns in customer feedback represent a real risk for a 25-year system investment. Before choosing Power On Solar, establish written service terms and verify emergency contact protocols. For most homeowners who want both quality installation and reliable long-term support, Century's veteran track record and consistent responsiveness across the project lifecycle make them the safer choice.

Frequently Asked Questions
Yes, because solar installation intersects directly with roofing integrity. A veteran contractor is better equipped to identify hidden structural issues, aging roof components, or flashing problems that could void warranties or cause leaks after panels are installed. Century's three decades of roofing experience means they've seen complications that a solar-focused contractor with 7 years may not anticipate until they become expensive problems.
Solar systems require 25 years of monitoring, maintenance, and occasional troubleshooting for inverter issues, panel connectivity, or weather damage. Multiple customers report difficulty reaching Power On Solar for post-installation problems, with some repairs taking extended periods. If your system goes offline and you can't get timely support, you lose both energy production and savings every day until it's fixed.
Warranty claims and system-specific troubleshooting typically require the installing contractor's involvement, and many warranties are voided if another contractor performs unauthorized work. Switching service providers is possible but often complicated and expensive. It's far better to choose a contractor with demonstrated service reliability from the start rather than plan to work around their limitations.
Yes. Even on newer roofs, solar installation requires proper flashing, waterproofing around mounting points, load distribution assessment, and coordination with roof warranty requirements. Century's 30 years means they understand how different roof materials age and can ensure panel mounting won't create problems years down the line. They also handle any roof repairs needed in one contract rather than requiring you to coordinate between separate companies.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
